MECHANISM FOR HEADING AND BENDING WIRE SPOKES.

SPECIFICATION forming part of Letters Patent No. 599,436, dated February22, 1898.

Application filed October 2, 1897.

To aZZ whom it may concern:

Be it known that 1, JOHN BATEY, a subject of the Queen of Great Britain,residing at 47 Heytesbury street, Dublin, Ireland, have invented certainnew and useful improvements in mechanism for forming a head on one endof wire spokes for wheels and for bending over'this end at an angle, ofwhich the following is a specification.

Wire spokes for wheels have to have a screw-thread cut on one of theirends and a head formed on themat the other end, and this latter end hasalso to be bent over at an angle. To thus form a head on one end andbend it over at an angle, I employ a machine constructed as hereinafterdescribed. In this machine the wires which are to be headed and bent areplaced into a hopper, from which they pass, one by one, into grooves cutlongitudinally along the circumference of a roller, to which astep-by-step revolving motion is imparted, one of the grooves in theroller being brought at the end of each partial turn below the hopper,so that a wire may drop into it. As the roller turns, the wires in thegrooves are carried around with it and are brought into successivepositions in which the wires are gripped and held firmly into thegrooves and prevented from moving endwise. While so held in the first ofthese positions, the end of the wire is subjected to repeated blows froma small hammer and may be treated in a similar manner by a second hammerat the second position and, if desired, by a third hammer in a thirdposition, and at the last of the positions the end of the wire is bentover at an angle. Finally the wire is carried around to a portion inwhich it is allowed to drop out of the groove in which it was lyingandis discharged from the machine.

The drawings hereunto annexed show a machine constructed in the abovemanner.

Figure 1 is a side elevation, and Fig. 2 an end View, of the machine,the lower part of the frame being cut away. Fig. 3 is a horizontalsection on the line a b, Fig. 2, of that end of the machine at which thewires are headed and bent. Fig. i is a section taken through one of thetoggle-lever grippers, and Figs. 5 and 6 are separate views of the swagemechanism for bending the headed ends of the wires. Fig. 7 showsseparately the roller Serial No. 653,785. (No model.)

spindle, with one end disk or portion of the roller fast with it. Theother disk or portion of the roller may be movable along the spindle tosuit different lengths of wire. Fig. 8 is a side elevation, and Fig. 9is an end elevation, of one of the cylinders E, carrying the incline EFig. 10 shows one of the guides S separately.

In the figures, A is the hopper containing the wires to be headed andbent. The throat or delivery-mouth of the hopper is a narrow channeldown which the wires descend in a horizontal position, one above theother, in a single layer. Below the end of the narrow throat is a rollerB, having longitudinal grooves formed along its circumference. Theroller might be a solid roller; but preferably it is, as shown, formedof aspindle B, carrying two disks B, one fast with one end of thespindle and the other movable along the spindle, so that it may be fixedto it at any desired distance from the first disk. The ends of thespindle are supported by fixed pivotpins 0 D. Each disk or end of theroller B is surrounded by a short cylinder E, part of which is cut awaywhere the hopper-mouth passes through it and where the wires aredischarged from the machine. The short cylinders E may be carried by or.form part of standards F G, which are fixed to the bed of the machine.The standard F has a short axis F projecting horizontally from it. Thespindle B passes freely through the center of this axis, and a cam-wheelH can revolve freely around its exterior.

B is a ratchet-wheel fast on the spindle B. By it a step-by-steprevolving motion is given to this wheel and so to the roller B by a pawlB The pawl has motion given to it from a rocking lever B, one arm ofwhich is acted on by a cam projection II on the cam-wheel H. Thecircumference of the wheel H is formed as a cog-wheel. A pinion I on adriving-shaft I gears with the teeth of this wheel, and a continuousrevolving motion is so imparted to it. The driving-shaft is carried inbearings fixed to the bed ofthe machine.

In the outer face of the cylinder G, which surrounds the other end ofthe roller B, are three radial grooves. In each of these radial grooveslies a slide J, which can be moved toward or away from the roller B bytoggle-le vers J. One end of these levers is jointed to the slide andthe other to a block J fixed to the cylinder G at the outer end of theradial groove. The central joint of the toggle-levers has a rod Lconnected to it. This rod is led away parallel with the axis of theroller B, and at its farther end carries a roller L, which lies in acam-groove L formed around the boss of the cam-wheel H, and by thiscam-groove an endway to-and-fro motion is imparted to the rod, and thetoggle-levers are thereby alternately caused to thrust the slide J up tothe roller 13, so that it may nip and hold one of the wires lying in agroove in this roller, and subsequently to move the slide J away fromthe roller and release the wire. The rod L at its end which carries theroller L is square and is supported by guide blocks L carried by thestandard F, and is guided by them in its to-andfro motion. The rods arein two parts, connected by short coupling-tubes L with right and lefthand screw-threads, so that their length may be adjusted and each slideJ, when moved up to the roller B, be thereby caused to grip the wirethat is lying opposite to its end with sufficient firmness.

M is a plate secured to the face of the cylinder G. By it the slides Jare retained within the radial grooves in the cylinder. Standing outfrom the outer face of the plate M are three pairs of projections M. Oneend of a radial hammer-arm N is jointed to each pair of projections. Theother end carries a hammer-head N. The hammer-arms are radial and eachtime that the roller 13 is brought to rest one or other of the groovesin it is brought into the same radial plane as each arm. The arms alsoare each of such a length that the hammer-heads carried at their endsmay strike against the ends of the wires carried in such grooves. Oneend of a rod N is jointed to each hammer-arm N. The rod extends throughopenings in the standard G and through guides in the standard F, and atits farther end carries a roller N which is acted on by a notchedcam-surface N formed around the inner face of the cam-wheel H near itscircumference. One end of a coiled spring N bears against a collar onthe rod. The other end of the coiled spring bears against oneffor otherof three arms which extend outward from a cylinder 0. This cylinder isconcentric with the roller 13 and extends from the standard F to thestandard G and forms part of the fixed frame of the machine. The threearms extending out from the cylinder 0 also carry guide blocks to guideand steady the rods L and N in their to-and-fro movement.

P is a bracket fixed to the plate M and carrying a pivot-pin D forsupporting the end of the spindle B. The plate also carries on its innerface a block Q. The block fits against .the circumference of this end ofthe roller B and relieves the pivot-pin D from all strain at the timewhen the slides J are thrust inward toward the roller and are nippingwires contained in its grooves.

The short cylinder E, which surrounds the end of the roller 13 farthestfrom the hammers, has a plate E fixed to its outer face. The ends of thewires lying in the grooves in the roller B rest against the inner faceof this plate. After each wire has been brought into position for itsopposite end to be acted upon by two of the hammers and as it is beingcarried around to be brought into position to be acted on by the thirdhammer an incline E on the plate E" (see Fig. 8) causes the wire to bemoved a short distance endwise along the groove in which it is lying.The end of the wire which has a head formed upon it is thereby made toproject somewhat more beyond the outer or swage face of .the roller Band beyond the outer face of the slides J, which is in the same planewith it, in order that this end of the wire may be bent over at anangle. The bending over of the end of the wire is effected by a swage R,jointed to an arm P which extends from the bracket P. Normally the swageis held at an angle to the face of the roller B by a spring R, as shownat Fig. 6. The third hammer is caused to strike three or other number ofblows on the swage and thereby to bend over the wire to the desiredextent,

The action of the apparatus is as follows: The roller B is rotated witha step-by-step movement by the action of the cam projection H on thecam-wheel H. At the completion of each partial rotation one of thegrooves in the roller Bis below the mouth of the hopper and a wire dropsfrom the hopper into the groove, At the same time other wires in othergrooves in the roller B are brought into positiOn to be acted on by thethree hammers. As the cam-wheel H continues its rotation the cam-grooveL formed around the boss of the cam-wheel H, causes the wire which is tobe acted on by the first hammer to be gripped and held in the groove inwhich it lies, and while it is so held the first hammer is caused tostrike three blows upon its end by the action Of three inclinedprojections of the camsurface N of the cam-wheel I-l. Each inclineacting on the roller N thrusts the hammer back, and when the summit ofthe incline has tinued rotation of the cam-wheel, the camsurfaces L andN cause the wire which is to be acted on by the third hammer to begripped and held and the swage which is to bend over its end to bestruck three or, it might be, a less number of blows by the hammer. Ifthis scend into the wider depressions and not into hammer is to strike aless number of blows, this may be effected by making the depressions inthe cam-surface N of varying sizes and by making the roller by whichthis hammer is actuated of such a size that it can dethe narrow ones. Inthe one case the hammer strikes a blow and in the other does not strikea blow. After the third hammer has struck its blow or blows thecam-surface H causes the roller B to make another partial turn. The wirewhich has thus had its end bent over is carried into a position wherethe wire is free to drop out from the groove in which it was lying andpasses from the machine and the same operations are repeated.

S S are guides between which the hammerarms pass as they strike a blow.These guides are fixed to the plate M, as shown in Figs. 2 and 3.

What I claim is 1. The combination of the hopper,the roller havinggrooves formed along its circumference, mechanism for giving astep-by-step revolving motion to the roller, the grippingblocks forgripping some of the wires to the roller close up to one of its ends,each time that the roller comes to rest, and hammers for striking theends of the wires while they are so held.

2. The combination of the hopper, the grooved roller, means for giving astep-bystep revolving motion to the roller the gripping-blocks forgripping some of the wires to the roller close up to one of its endseach time that the roller comes to rest, the toggle-levers actuatingthese blocks,the hammers for striking the ends of the wires while theyare so held, and the three revolving cams one imparting movement to themechanism used for giving a step-by-step revolving motion to the roller,another actuating the hammers, and the third actuating the toggle-leverswhich impart movement to the gripping-blocks.

3. The combination of the hopper, the

grooved roller, means for giving a step-bystep revolving motion to theroller, the grip ping-blocks, the toggle-levers actuating these blocks,the hammers, the three revolving cams, one imparting movement to themechanism used for giving a step-by-step revolvin g motion to theroller, another actuating the hammers and the third actuating thetogglelevers which impart movement to the gripping-blocks, the inclinefor shifting the wires a short distance endwise after they have beenacted on by one or more of the hammers, and the hinged swage struck bythe last hammer for bending over the headed ends of the wires which havebeen so moved endwise.
